Google Webmaster Tools seems to be giving me an erroneous report. The crawl Errors (Smart Phone tab) still shows a link to http://mypubguide.com/good-pubs/Blacko from http://mypubguide.com/good-pubs/blacko-in-pendle-district
I cannot find any such link when I view source or use web kit to search for it. This been going on for a while but this comes back after being marked as fixed and it's on the report as being detected today.
Caching policy in the web.config is set to 30 minutes:
var foo = '/Blacko';
in JavaScript as if it were a URL. I don't see anything like that in your page now, but that report has a tendency to report links it may have found months ago. – Stephen Ostermiller♦ Jun 29 '16 at 11:38
